My current understanding of Uniswap V3 the following code is required to get the address of a pool:
getPool(tokenA, tokenB, FEE)
My problem at this stage is I need to GUESS what the fee could be. I see they are sometimes 0.05% and other times 0.3% or anything inbetween.
How can I get all the pools for tokenA and tokenB without specifying a fee ?
